Mass motions in the atmospheres of red giant stars in the globular cluster M4.

KEMP S.N. and BATES B.

Abstract (from CDS):

High-resolution line profiles of the Na D and Hα stellar lines of red giant stars in the globular cluster M4 are presented and examined for the presence of features indicative of mass motions in the stellar atmospheres. Such features include emission in the wings of the Hα line and blueshifts of up to ≃-10km/s in the cores of the Na D and Hα absorption lines relative to the photospheric radial velocity of the star. We discuss correlations between these observed parameters, and examine the location of the stars showing such phenomena on a Hertzsprung-Russell diagram.
Result. are compared with those from our previous study of stars in the ω Cen and M22 clusters (Bates et al. 1993), and with other literature studies. We also discuss a re-evaluation of the stellar parameters obtained by assigning individual E(B-V) values to each star, based on our measurements of interstellar K I column densities, to examine how this affects these correlations and the appearance of the HR diagram.
